. SPECIFICATION forming part of Letters Patent No. 489,610, datedJanuary 10, 1893.

Application filed September 17, 1892- Serial No. 446,217. (No model.)

To all whom, it nuty concern.-

Be it known that I, J OHN W. LICKEY, a citizen of the United States,residing at Rushville, in the county of Schuyler and State of Illinois,have invented a new and useful Lifting Device, of which the following isa specification.

My invention relates to a lifting device designed for elevating stoves,boxes, articles of furniture, freight &c., the object in view being toprovide means for moving such articles from place to place withfacility.

Further objects and advantages of the invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings:--Figure 1 is a perspective View, showing a stoveelevated by means of my lifting device. Fig. 2 is a side view of thelifting device. Fig. 3 is a transverse Vertical sectional view, uponline 00 0c of Fig. 2, looking rearward, and showing in dotted lines anadjusted position of one of the side frames, the lifting frames beinglowered close to the floor. Fig. 4 is a longitudinal sectional view.

Like letters of reference indicate corresponding parts in all thefigures of the drawlngs.

A A represent the parallel longitudinal base bars connected at one endby the transverse slide B, which fits in suitable openings in said basebars and by sliding therein enables said base bars to be adjustedlaterally with relation to each other. Rising from these base bars aretoothed uprights O 0 upon which are arranged the lifting frames D. Theseframes consist, essentially, of the operating levers E, provided nearone end with an opening 6 to receive the upright to which it is attachedand also pivotally connected adjacent to said opening by means ofvertical hangers F to the horizontal supporting bar G. The operatinglevers are connected near their free ends by a transverse round H, whichis adapted to slide in the openings formed in said levers to enable thelifting frames, which are carried by the uprights, to be adjustedlaterally. Pivoted operating pawls K are connected in pairs to theoperating levers, and are connected together in openings e of theoperating levers.

pairs by the actuating springs L, said pawls being arranged to engagethe teeth upon opposite edges of the uprights. The pawls are connectedby means of rods M to the bellcrank levers N, located respectively uponopposite sides of the operating levers in proximity to the connectinground, the upper arms of said bell-crank levers projecting toward eachother to enable the operator to depress both of the bell-crank leversupon each operating lever simultaneously.

The uprights O are provided with vertical slots 0, in which slidetransverse guide pins 0, which are arranged transversely in the Saidopenings are of sufficient length to enable the operating levers toswing vertically at their free ends in order to enable the pawls sue.-cessively to engage the teeth upon opposite edges of the uprights.

The supporting bars, which are adapted to extend along the sides of thearticle to be elevated, are provided with pivoted arms P, designed to beswung inwardly to engage under said article. These supporting bars arefurther provided with depending hooks Q, which may be brought close tothe floor to pass under an article which rests closely thereupon, suchas a box, or barrel.

In operation, when it is desired to elevate a stove, or other article,the lifting frames are depressed by withdrawing the springactuated pawlsfrom engagement with the teeth of the uprights by depressing the upperarms of the bell-crank levers. After swinging the pivoted supportingarms under the article to be elevated, the free ends of the operatinglevers are elevated and depressed alternately to cause the pawls toengage opposite series of teeth, successively, as will be readilyunderstood.

The base bars are provided, as shown in the drawings, with casters orwheels R, and to the transverse slide bar is attached a tongue S, toenable my improved lifting device to perform the functions of a truck inconveying articles from place to place.

Changes in the form, size and proportions of the parts and also in theminor details of construction may be resorted to Without departing fromthe spirit or sacrificing any of the advantages of my invention, and Ireserve the right to make such changes within the scope of my invention.

Having described my invention, what I claim, is:-

1. In a lifting device, the combination with uprights provided withopposite series of teeth, of the operating levers provided withelongated openings to receive said uprights, spring-actuated pawlsarranged at opposite sides of said openings to engage opposite series ofteeth upon the uprights, and means to withdraw said pawls fromengagement with the teeth, substantially as specified.

2. Ina lifting device, the combination with oppositely toothed uprights,of the operating levers provided with openings to receive said uprights,spring-actuated pawls to engage opposite series of teeth upon theuprights, and bell-crank levers connected respectively to the pawls andarranged in pairs, substantially as specified.

3. In a lifting device, the combination of the toothed uprights providedwith longitudinal slots, the operating levers provided with openings toreceive the uprights and having transverse guide pins arranged in saidopenings to slide in the slots, the spring actuated pawls carried by theoperating levers, and means to retract said pawls simultaneously,substantially as specified.

4. The combination of toothed uprights, operating levers slidablymounted upon said uprights, and carrying spring-pressed pawls to engagethe teeth thereof, and horizontal supporting bars G slidably mountedupon the uprights and connected to the levers by hangers, substantiallyas specified.

5. The combination with toothed uprights, operating levers slidablymounted thereupon and carrying spring-pressed pawls to engage the teeth,and supporting-bars suspended by hangers from the operating-levers, ofarms P, pivoted to said supporting-bars and adapted to be extended toengage an article to be elevated, substantially as specified.

6. The combination with toothed uprights, and operating-levers slidablymounted thereupon, and carrying spring-pressed pawls of supporting barsG slidably mounted upon said uprights, and pivotally connected to thelevers, and hooks Q carried by said bars to engage articles to beelevated, substantially as specified.

7. The combination of twin uprights provided with horizontal baseportion, a transverse slide fitted into openings in said base portionswhereby the uprights may be laterally adjusted, and lifting mechanismmounted upon the uprights, substantially as specified.

- In testimony that I claim the foregoing as my own I have heretoaffixed my signature in the presence of two witnesses.
